Video analysis is available for footage that requires any kind of behavioural evaluation. For cases requiring deception detection, it is beneficial for SDL to have access to video footage for the most accurate analysis.

SDL analysis work has included police interviews, TV interviews, personal home videos, national magazine photo analysis, and work with universities.

FACS: Using FACS, SDL can code, identify and explain thousands of emotional reactions expressed through both voluntary and involuntary facial movements. Coding can be applied to images or videos. To learn more about FACS, click here.

Deception Detection Tip: "Watch for incongruence in a person's words, facial expressions, and body language. Liars often struggle to keep them all in sync, whereas truth-tellers will broadcast the same message consistently across all channels."
